It's not fair.

Esme has the ability to turn you into a vampire just like her, so you'll be with her forever, but you continue to deny her. What's so great about being human, anyway? But she'll respect your wishes. Even if it pains her, she would never force you.

Even now, as you sit next to her while she bandages your wounded leg, she still allows you to stay human, as long as you are happy.
